The Recombinant (E. coli) Hepatitis B Surface Antigen preS2+S (HBsAg/Genotype B, 1-445 aa, ~50 kda>95%, His-tag) is manufactured for Research Use Only or for diagnostics purposes.
Antigens are peptides or recombinant or native dependent on the production method.Hepatitis a, b, c, d, e recombinant surface viral antigens to genotype 1, 2, 3, 4, 5 are used for antibody production to make diagnostic poly or monoclonal antibodies. Hepatitis is a disease of the liver characterized by the presence of inflammatory cells in the tissue of the organ. Hepatitis may occur without symptoms, but can lead to jaundice (a yellow discoloration of the skin, mucous membranes, and conjunctiva of the eyes), poor appetite, and fatigue. Depending on the cause, hepatitis can manifest either as an acute or as a chronic disease.The kilo Daltons subunit weight of Recombinant ( ) Hepatitis B Surface Antigen preS2+S (HBsAg/Genotype B, 1-445 aa, ~50>95% His-tag) compared to your protein ladder can be shifted a little due to electrophoresis effects. 1 kDa = 1000 g/mol protein
